SPECIFICATION forming part of Letters Patent No. 736,172 dated August 11, 1903.

Application filed October 80,1902. Serial No. 129,404- (No model.)

To all; whom it may concern: r

Be itknown that we, MAURIon W. ,TALEN, CARL F. PEARSON, ERICK B. CHRISTOPHER,

and GUSTAF E. Jonnson, citizens of -the United States, and Lime A. LINDBERG, a subject of the King of Sweden and Norway, all1 residents of Chicago, in the county of Cook; and State oflllinois, have invented anew and Improved Vehicle Driving-Gear, of which; IO. the following is a full, clear, and exact description. This invention is intended particularly for use on automobiles, and relates to certain novel features residing in a speedchange 15 transmission-gear of the sun-and-planet type and ma novel construction bywhich this gear is combined with a diiferentialgearing in such a manner as to form, as Willbe hereinafter fully set forth, a concrete gearing servingthe 2o two functions referred to.

gear and part of the transmission-gear; and

Fig. 4is an outer end elevation of the clutch,

as shown in Fig. 3.

39 and 40 represent, respectively, the two parts of the divided driving-axle or other divided element to be driven. To these parts are respectively fastened the spur-gears 41 40 and 42 of the differential gear. These gears are inclosed in a case 43,in which are men nted the intermeshed pinions 44, these pinions being also meshed, respectively, with the gears 41 and42. The gear-case 43 carries the inner 45 clutch member,which is arranged to turn with the gearcase and which comprises the segmental shoes 45. These shoes each have studs 46 at one end, said studs being fastened in the Fig. 3 is a fragmentary view showing the differential gear-case 43, whereby to mount the shoes.

The opposing ends of the shoes have beveled 50 faces 45, and between these faces work the wedges 47, said wedges being carried on Iovers 48,con nected by 1inks49 with the collar 50, this collar being loose on the axle-section 40, so as to move independently thereof. The right-hand hub 43 of the gear-case 43 is loosely mounted on the-axle-section 40, and the left-hand end carries a sleeve 51, which loosely encircles the axle-section 39 and to which is attached a gear 53. On said sleeve 51, between the gear 53 and the case 43, is mounted a sleeve 58, to which is attached the driving sprocket-wheel 59, andsaid sleeve is extended outwardly and laterally to form a circular clutch member 60, inclosing the shoes 45 and coacting therewith to form the complete clutch. The sleeve 58 is loose on the sleeve 51, and said sleeve 58 carries a gear 57,lying alongside of the gear 53. Lying at the opposite side of the gear 53 and loose on the shaft-section 39 is a gear 61, fastened to a sleeve 62, and said sleeve carrying a brake -wheel 63, to which a strap -brake or other means for retarding the revolution of the parts 63, 62, and 61 is applied. 52 indicates a gear-case which incloses the gears 57, 53, and 61 and which has its hubs 52 bearing, respectively, on the sleeve 58 and on the sleeve 62. In said gear-case 52 are three connected planetary gears 56, 54, and 55. Of these gears the gear 56 meshes with the gear 61, the gear 54 meshes with the gear 53, and the gear 55 meshes with an intermediate gear 64, (see Fig. 2,) said intermediate gear 64 in turn meshing with the gear 57. The gearing as thus organized provides for high and low speed ahead and a reverse movement. High speed is attained by throwing in the clutch, so that the case 43 is in rigid connection with the driving sprocket-wheel 59. Transmis- 9o sion is then direct, and the gears 44 and 41, acting with the divided axle, allow for the difference in movement of the two axle-sections, as will be understood." To obtain low speed ahead, the brake-band should be tight- 9 5' ened on the wheel 63, thus arresting the gear 61. The driving-gear 57, acting through the gears 64 and 55, will cause the planetary gears and their case to roll around the thenstationary gear 61, and owing to the ratio between the gears 54 and 53 the sleeve 51 will be driven in the same direction as the gear 57, but at a lower speed. To reverse the direction of movement, the brake wheel 63 should be released, thus causing the gear ele-' subject to the operation of the differential spirit and scope thereof.
